ganglia2pcp - import ganglia data and create a PCP archive

ganglia2pcp is intended to read a set of ganglia files stored in the rrd format and translate them into a
       Performance Co-Pilot (PCP) archive with the basename outfile.

       The intent of this converter is to take all of the rrd files found in the input_dir and generate a single
       pcp archive file.  The mapping of ganglia metrics to pcp metrics is defined internally.

       The resultant PCP achive may be used with all the PCP client tools to graph subsets  of  the  data  using
       pmchart(1), perform data reduction and reporting, filter with the PCP inference engine pmie(1), etc.

       A series of physical files will be created with the prefix outfile.  These are outfile.0 (the performance
       data),  outfile.meta  (the  metadata  that  describes the performance data) and outfile.index (a temporal
       index to improve efficiency of replay operations for the archive).  If any of these files exists already,
       then sar2pcp will not overwrite them and will exit with an error message of the form

       __pmLogNewFile: ``blah.0'' already exists, not over-written

       ganglia2pcp is a Perl script that uses the PCP::LogImport  Perl  wrapper  around  the  PCP  libpcp_import
       library,  and  as  such  could  be  used  as  an  example  to  develop new tools to import other types of
       performance data and create PCP archives.  The RRDs Perl wrapper is used to  parse  the  raw  rrd  format
       files.

       The available command line options are:

       -doutdir
            The outdir argument specifies a output to write to.  The default is the current directory.

       -eend
            The end argument specifies a end time in a format understood by str2time.  The default start time is
            current time.

       -foutfile
            The  outfile  argument  specifies  a output file name.  The default name is in the standard pmlogger
            format based on the start time, e.g., 20150201.00.10.

       -hhostname
            The hostname argument specifies a hostname to write to the archive.  The default is taken  from  the
            directory name that the rrd files reside in.

       -sstart
            The  start  argument  specifies  a start time in a format understood by str2time.  The default start
            time is 24 prior to current time.

       -Vversion
            The -V option specifies the version for the output PCP archive.   By  default  the  archive  version
            $PCP_ARCHIVE_VERSION  (set  to  3  in  current  PCP releases) is used, and the only values currently
            supported for version are 2 or 3.

       -Ztimezone
            The timezone argument sets the source timezone in the PCP archive (the default is to use  the  local
            timezone).   The  timezone  must  have the format +HHMM (for hours and minutes East of UTC) or -HHMM
            (for hours and minutes West of UTC) or UTC.  Note in  particular  that  neither  the  zoneinfo  (aka
            Olson)  format,  e.g.  Europe/Paris,  nor  the  Posix  TZ  format, e.g.  EST+5 is allowed.  Example:
            timezone=``+1100''.

       Environment variables with the prefix PCP_ are used to parameterize the file and directory names used  by
       PCP.   On  each  installation, the file /etc/pcp.conf contains the local values for these variables.  The
       $PCP_CONF variable may be used to specify an alternative configuration file, as described in pcp.conf(5).
